Cloud Migration for Accounting Firms in Pittsburgh

Tax season does not pause for a server failure, and your clients do not care whether CCH, Lacerte, UltraTax, QuickBooks, or Sage lives on a box in the back closet or in Azure. They care that their return is filed, their books close on time, and their data is not sitting on a stolen laptop. If your firm is weighing a move off aging on-prem hardware or an expensive hosted-desktop bill, cloud migration for accounting firms is the project that determines whether the next three busy seasons are calm or chaotic.
PGH Networks plans and executes cloud migration for accounting firms across the Pittsburgh metro — from Downtown and the Strip District out to Cranberry, Wexford, Monroeville, Robinson, Washington, and Greensburg. We handle the full lift: assessment, licensing, identity, data, security controls, and the cutover weekend itself, with your tax and audit software vendors looped in from day one.
Who this is for
This page is written for managing partners, firm administrators, and IT directors at CPA and accounting practices roughly 10 to 250 seats. You are usually in one of three situations: a Windows Server or SBS box is past end-of-life and the CPA on the hook for signing off on internal controls is nervous; a third-party hosted-desktop provider has been raising prices every renewal and support has slipped; or the firm has grown through acquisition and now runs three tax stacks, two file servers, and a VPN nobody trusts. Remote and hybrid staff, seasonal preparers, and client portals all need to work from anywhere without a Citrix bill that rivals payroll.
If you are a sole practitioner running one workstation, you probably do not need us. If you have a mixed environment with a domain controller, a practice management database, a document management system like SmartVault or Doc.It, and a compliance obligation you can name out loud, you are in the right place.

What a cloud migration for accounting firms actually includes
A real migration is not "move the files to SharePoint and hope." We start with a readiness assessment that inventories every application, every integration (bank feeds, e-file, portals, payroll connectors), user identity, data volume, and the compliance controls you already claim to have. From there we design the target state — usually a mix of Microsoft 365 with Entra ID, Azure Virtual Desktop or Windows 365 for tax-engine workloads that still need a Windows session, and SharePoint or a purpose-built DMS for working papers.
The hard part of moving an accounting firm to the cloud is not the data copy, it is preserving the exact application behavior your preparers rely on during a 90-day filing window.
Execution covers identity cutover and MFA rollout, data migration with chain-of-custody logging, application repackaging or vendor-hosted integration for CCH Axcess, Thomson Reuters CS Professional Suite, Wolters Kluwer, Caseware, or Sage Intacct, printer and scanner remediation (yes, this is where migrations die), and a rehearsed cutover with a documented rollback. After go-live, ongoing managed IT, patch management, and a staffed help desk keep the environment healthy so partners are not IT-support-by-text-message on April 14th.
Compliance and security built into the migration, not bolted on
Accounting firms sit on W-2s, SSNs, bank credentials, K-1s, and closing binders. That makes you a target and a regulated entity. Every migration we run for a CPA firm is designed against the IRS Publication 4557 Written Information Security Plan requirement, the FTC Safeguards Rule under GLBA, and — where clients demand it — SOC 2 Type II readiness. If you serve healthcare clients or handle PHI in an audit, HIPAA obligations come with you into the cloud.
TL;DR: A cloud migration for accounting firms only pays off if identity, endpoint, email, and data-loss controls are enforced by policy on day one, not added the next time an auditor asks.
Practically, that means conditional access with phishing-resistant MFA, EDR on every endpoint, Microsoft Purview or an equivalent DLP policy scoped to tax-return data, immutable backups tested quarterly, and an incident response runbook your partners have actually read. If your firm subcontracts to defense-industry clients, we can also align controls with CMMC Level 2 so a single stack serves both practices.

Why PGH Networks
We are a Pittsburgh-based MSP, not a national hosting reseller. That matters when a partner needs someone on-site in Fox Chapel on a Saturday, or when your Sewickley office loses fiber the morning K-1s are due. Our team knows the tax and audit application landscape, the quirks of e-file transmission through vendor cloud gateways, and the specific ways CCH, Thomson, and Intuit expect their software to be licensed and hosted.
We also run a working AI advisory and AI workflow automation practice, which matters because your next three years of productivity gains — Copilot for drafting engagement letters, document automation for PBC lists, structured extraction from client-supplied PDFs — depend on the cloud foundation you build now. Migrating without thinking about how Copilot, Azure OpenAI, and a future custom AI application will use that data is how firms end up re-doing the project in 2028. A vCIO stays engaged after cutover to keep the technology roadmap aligned with partner-group priorities.
Next step
If you want a fixed-scope readiness assessment before your next renewal or busy season, we can usually deliver findings in two to three weeks.
Call 724.888.7007 or send the basics through the contact form and we will set up a scoping call with an engineer who has migrated firms that look like yours.
